Be careful with the plastic end piece that fits into the speedo.
They tend to break. You can actually get just the end fitting and a ferrule to clamp it on from some specialty companies. The firewall gasket is also available.
A non-tilt Mopar column is so close to one of the General’s parts (and the tilt column is basically a GM part whole cloth) that it likely doesn’t matter.
I’d check to see if the one you have has slipped at the shear “pin” in the collapsing shaft which can cause a lot of issues and its isn’t...
